A new study suggested that Neurofeedback, also called 'brain training' may be an effective treatment for individuals with post-traumatic stress disorder (PTSD).The findings of the study were published in the journal 'Neurolmage: Clinical'. Neurofeedback consists of exercises where individuals regulate their own brain activity.In the study from Lawson Health Research Institute and Western University, researchers have found that neurofeedback may be an effective treatment for individuals with post-traumatic stress disorder (PTSD)."Brain connectivity involves different parts of the brain communicating with each other and helps to regulate states of consciousness, thought, mood and emotion," explained Dr. Ruth Lus, a scientist at Lawson, professor at Western's Schulich School of Medicine & Dentistry, and psychiatrist at London Health Sciences Centre."Individuals with PTSD tend to have disrupted patterns of brain connectivity, but our research suggests they can exercise their brains to restore patterns to a healthy balance," added Lus.Neurofeedback uses a system called a neurofeedback loop in which a person's brain activity is measured through sensors placed on the scalp and displayed back to them using a computer interface. This allows the individual to complete exercises and visually see the results.The trial tested neurofeedback with a total of 72 participants, including 36 participants with PTSD and 36 healthy control participants. Of those with PTSD, 18 were randomized to participate in neurofeedback treatment while the other 18 acted as a comparison group.The study found that the severity of PTSD symptoms decreased in participants randomized to receive neurofeedback treatment. After treatment, 61.1 per cent of participants no longer met the definition for PTSD. This remission rate is comparable to gold standard therapies like trauma-focused psychotherapy.The research team also used functional magnetic resonance imaging (fMRI) at St. Joseph's Health Care London to capture brain scans of participants both before and after participation in the trial. They found that individuals with PTSD experienced positive changes in brain connectivity in the salience network and the default mode network following neurofeedback treatment."The salience network is involved in detecting threat as part of the 'fight or flight' response. It is normally hyperactive in individuals with PTSD. Meanwhile, the default mode network is activated during rest and is involved in autobiographical memory. We often see that this network is less active during rest and functionally disrupted among individuals with PTSD," said Dr. Andrew Nicholson, an affiliated scientist at Lawson."Neurofeedback helped restore the functional connectivity of both networks to healthier levels," added Nicholson.The study involved weekly sessions of neurofeedback over 20 weeks. Participants were asked to reduce the intensity of the brain's dominant brain wave - the alpha rhythm. Brain activity was visualized as either a still cartoon or a distorted picture. If the alpha rhythm was successfully reduced, the cartoon started playing or the picture started becoming clearer."Participants were not instructed on how to reduce the alpha rhythm. Rather, each individual figured out their own way to do so," noted Dr. Lus. "For example, individuals reported letting their mind wander, thinking about positive things or concentrating their attention."The team noted the treatment could have a number of clinical implications following further validation."Neurofeedback could offer an accessible and effective treatment option for individuals with PTSD. The treatment is easily scalable for implementation in rural areas and even at home," said Dr. Lus.( With inputs from ANI )Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
